Siemens SINAMICS G120 Come iniziare
Installing
3.2 Installing Control Unit
Requirements
● Use suitable cables:
– Solid or flexible cables.
– Suitable cable cross-section: 0.5 mm² (21 AWG) to 1.5 mm² (16 AWG).
● Do not use end sleeves.
● You have found an appropriate pre-assignment for the terminal strips, which you can now
use to wire the inverter.
See also Section Finding a suitable setting for the interfaces (Page 25).
● You have the appropriate tools:
– Small screwdriver to open the spring-loaded terminals
– Tool for stripping the cables
Procedure
To connect up the inverter's terminal strip, proceed as follows:
1. Remove the last 10 mm (approx.) of the cable insulation.
2. Using the screwdriver, press on the orange operator control of the spring-loaded terminal
hard enough to open the terminal.
3. Insert the cable into the terminal as far as it will go and remove the screwdriver.
4. Ensure that the cable is securely connected by pulling on it lightly.
5. Connect up all of the required terminals on the terminal strip in this way.
6. Route the signal cables in such a way that you can completely close the front doors after
wiring the terminal strip.
7. If you use shielded cables, then you must connect the shield to the mounting plate of the
control cabinet or with the shield support of the inverter through a good electrical
connection and a large surface area.

When completely connecting up the unit, we recommend cables with a cross-section
of 1 mm² (18 AWG).
